Note that during testing I discovered the web proxy server doesn't startup successfully due to a missing directory and filed YARN-363. I'm not considering that a blocker since the missing directory can be created manually or the user can run the web proxy as part of the RM as a workaround.

I'm testing the RC without the native libs, and I'm seeing warning outputto stderr on some shell commands, similar to what is reported in HDFS-4427. (See example below.) Is this a known issue for the release?

+1 (non-binding), assuming the issue I mentioned earlier about the newwarning output is not considered a blocker.

I verified checksum and signature for hadoop-0.23.6.tar.gz. I ran a set ofUbuntu VMs: NN, RM, 2 * DN, 2 * NM, and 2NN. I tested multiple HDFSinteractions and MapReduce jobs. Everything worked as expected. The onlypotential problem I noticed was that new warning output.

If that is the case the work around is simply change that back toorg.apache.hadoop.security.ShellBasedUnixGroupsMapping or have nativelibraries so I don't think it would be a blocker. Unless others disagree.

I had not set hadoop.security.group.mapping in my config. I was inheritingShellBasedUnixGroupsMapping from core-default.xml.

I'm wondering if this is something a bit different. I only see the problemwhen running "hadoop fs -cat". I haven't seen it from any other command.

For further testing, I did trysetting JniBasedUnixGroupsMappingWithFallback in my config to see whatwould happen. When I do that, every command I run displays the warning. Switching back to ShellBasedUnixGroupsMapping, the warning only appearsfor "hadoop fs -cat" and no other commands.
